IMPROVEMENT IN STEAIVI-RADIATORS.v

Specification forming part of Letters' Patent No. 135,633, dated February 11, 1873.

To alL whom tmay concern:

Be it known that I, LEWIS S. DANIELS, of Foxborough, in the county of Norfolk and State of Massachusetts, have invented certain Improvements in Radiators, of which the followingis a specification The nature of my invention consists in a device for a radiator, in which are a series ot hollow vertical pipes, havin g a clear internal space, connected together at the top by tubes, also free internally, and having thedower ends of the said vertical pipes united to a horizontal pipe, which is provided with perforated diaphragms located between each pair ot' vertical pipes or columns, so as to cause a circuitous dow of steam. The object of this arrangement is to get a free ow of steam, and yet provide for the return of the water of condensation. The free circuitous low of steam is obtained by the arrangement of open pipes and the diaphragms in the horizontal pipe, while the direct flow of the Water of condensation is secured by the system of perforations in the lower part of the diaphragm. I

Figure 1 is an elevation illustrating my invention. Fig. 2 is a section otl the same, also showing, by dotted lines, additional pipes of the series.

Let D represent the horizontal pipe, to which the vertical pipes A and B are united at the lower ends. C represents a short horizontal pipe that serves to unite the pair of vertical pipes at the upper end. E, Fig. 2, is a diaphragm, so located in the lower horizontal pipe as to separate the pairs of vertical pipes. Inspection of the drawing will show that the diaphra-gms E and connecting-pipes C together cause a circulation of steam through all of the pipes, and, as there is no division-plate or other obstructions in the pipes themselves, the tlow of steam will be unimpeded. The diaphragms E are each provided with a small hole on a level with the bottom of the caliber of the lower pipe, so that the water may flow freely. This hole e through the diaphragm may be so small as not to allow any perceptible tlow otsteam, and yet allow the water to pass freely.

I claim as my invention- The radiator described, consisting ot' the vertical pipes A B unitedat the top by the pipe C and a-t the bottom by the pipe D, the pipe l) being provided with the separatingdiaphragm E provided at its lower edge with an opening, e, for the passage of the water.
